The alignment of spins in a ferromagnet is strongly influenced by its nanoscale geometry. This principle is applied in modern technologies, such as MRAMs, and is being investigated in more advanced and complex structures like artificial spin ice geometries. The primary imaging challenges are the extreme scaling and the delicate nature of the resulting magnetic textures. Using the ProteusQ, we successfully imaged ultrascaled nanowires as narrow as 6 nm and demonstrated our ability to capture fragile spin vortices and artificial spin ice textures without causing disturbances.
Swastik Kar’s group at Northeastern University used AC magnetometry on the Qnami ProteusQ to show that a permalloy nanowire can be used to concentrate RF fields into sub 300nm regions.
Researchers led by Jacopo Forneris have demonstrated the fabrication of germanium-vacancy (GeV) color center arrays in diamond nanopillars, showcasing the Quantum Foundry’s expertise in nanopatterning for quantum photonics.
